Whats the difference between a triangulated 4 link and a parallel 4 link? Which is better?
Both styles of 4 link accomplish the same thing… very simply, they hold the rear axle in the vehicle. The function of a 4 link is to keep the rear axle in its proper place under the vehicle. The bottom 2 links keep the axle in place front to back. The upper 2 links keep the axle from rotating, keeping the pinion angle as constant as possible.
